3 Claims.

This invention relates to means for dyeing yarn, and more particularly to means by which yarn packages may be wound and dyed in a form suitable for shipping, or for other subsequent use, directly after dyeing without requiring any re- .winding operation.

The means of the present invention constitutes an improvement of the invention disclosed in my prior U. S. Patent 2,489,465, which is directed to a perforated dye cone adapted for supporting a Wound yarn package for package dyeing in a form which allows the dyed yarn to be withdrawn directly from the dye cone without any intermediate rewinding step such as was required by the previous methods commonly in use. As disclosed in my above noted prior patent, this result is accomplished by forming the perforated dye cone with integral bushings at its top and bottom ends which are adapted to provide bearing surfaces for disposing the dye cone on a winder spindle for winding a yarn package thereon, and for stacking the dye cones after winding on a dye machine spindle for package dyeing. A further feature of this dye cone arrangement of my prior patent is the formation of the integral bushing at the bottom larger end of the dye cones with a recess for nesting over the top smaller end of an adjacent dye cone in stacking on a dye machine spindle so as to eliect the necessary seal between the stacked dye cones during the package dyeing operation.

Perforated dye cones formed in accordance with my prior patent give excellent results and are now being used successfully in actual commercial operations. The arrangement of these dye cones with integral bushings, however, necessarily complicates their structure somewhat so that it has not proved practical to for n a dye cone of this sort inexpensively enough to allow it to be used once and discarded as is common practice in many instances with textile yarn carriers. For example, it is often desired to ship yarn packages that have been dyed or finished in a plant at one place for subsequent use in a separate or independent plant located at another place, and in doing so there is considerable advantage in using warn carriers for supporting the dyed packages during shipment that are expendable so that there is no practical necessity for recovering them for reuse.

In accordance with the present invention,

means are provided by which yarn may be ham-- dledthrough a package dyeing operation on a yarn carrier formed of relatively inexpensive, expendable material suitable for use as a shipping core, while still retaining all of the advantages afiorded by the invention of my prior patent. Briefly described, this means of the present invention comprises an arrangement of an expendable yarn carrier, having perforated walls adapting it for package dyeing of a yarn package wound thereon, on a permanent, reusable adapter formed for supporting this yarn carrier during winding of a yarn package thereon and subsequent dyeing of the wound yarn package.

The adapter used in this manner according to the present invention comprises end portions forming bushings, as described in my above noted prior patent, which are adapted to provide bearing surfaces for the adapter and a supported yarn carrier on a winder spindle and on a dye machine spindle, and an intermediate connecting portion between these end portions arranged for allowing free access of dye liquid to the perforated walls of the yarn carrier when supported on the adapter. As a result, the winding of the yarn package and handling through the package dyeing operation may be carried out on the adapter and supported yarn carrier of the present invention in the same manner as described in my prior patent, while the yarn package after dyeing may be removed from the adapter and arranged for shipping, or for other subsequent use, directly on the expendable yarn carrier, thus requiring only a relatively small number of the more expensive adapters to carry out the package dyeing operation.

The present invention is described further below in connection with the accompanying drawing, in which:

Fig. 1 is an exploded side elevation, partly broken away, illustrating the relative form and arrangement for assembly of a yarn carrier and adapter in accordance with the present invention;

Fig. 2 is a longitudinal section illustrating the manner in which the assembled yarn carriers and adapters may be stacked; and

Fig. 3 is a transverse section taken substantially on the lines 3-3 in Fig. 2.

- Referring first to Fig. l of the drawing, a yarn carrier such as may be used in accordance with the present invention is indicated by the reference numeral I0, and, as shown, is provided in a conical form and has a suitable pattern of perforations l2 .formed in its walls to adapt it for package dyeing of a yarn package wound thereon. The conical form is provided inorder to facilitate direct withdrawal of the yarn package after dyeing, and for this purpose a taper of from ing agents to condition it with adequate physicalcharacteristics for use in package dyeing. Instead of a wound laminated paper structure, the yarn carrier might also be formed with a molded paper body, or any of the great variety of suitable plastic materials available might be used in forming it.

An adapter such as is used according to the present invention for supporting the yarn carrier I0 is shown in Fig. 1 at M, and as previously mentioned comprises end portions as at 5 and .18, each of which are formed with cylindrical internal bores 29 and 22 of the same diameter adapted to provide bearing surfaces for the adapter 14 and a supported yarn carrier It on a winder spindle and on a dye machine spindle. The adapter it has an external shape of conical form for supporting the yarn carrier it, and is formed in this shape between the end portions 14 and it by an intermediate perforate connecting portion arranged for allowing free access of dye liquor through the perforations 12 in the walls of the yarn carrier I0 when supported on the adapter M. The actual perforate form of this intermediate connecting portion may be arranged in a great variety of ways. It might be arranged with longitudinal slots, or with starshaped or other specially patterned openings, or with a pattern of openings corresponding with the pattern of perforations 12 arranged in the walls of the yarn carrier H], in which latter case it would be desirable to provide at least one notch as at 24 at the bottom edge of the yarn 5 carrier I0 for interfitting with a projecting lug as at 26 on the exterior surface of the adapter 14 adjacent its bottom end.

A preferred arrangement of the intermediate connecting portion of the adapter it comprises spaced rod members 28 of circular cross section arranged in any suitable manner, as with reduced ends 30, for fixed assembly with the adapter end portions i6 and [8. This arrangement of rod members 28 has the particular advantage of providing for free access of dye liquor through the yarn carrier perforations 12 because the circular cross section of the rod members 28 is adapted for allowing access of dye liquor to the perforations I2 even though one of these rod members 28 may be disposed directly at a series of yarn carrier perforations l2 (compare Fig. 3). In order to take full advantage of this feature it is, of course, desirable not to use any larger diameter for the rod members 28 than is necessary, and preferably a diameter not substantially larger than the diameter of the yarn carrier perforations [2. It would also be possible, if desired, to form the rod members 23 with a triangular or other comparable geometric cross, section and obtain similar results. In addition, the openings used to form the perforate connecting portion of the adapter It may be otherwise formed,

as previously mentioned, to obtain similar results so long as these openings extend laterally for a distance greater than the lateral spacing between the yarn carrier perforations 12, which arrangement would provide for access of dye liquor to the perforations I2 in any supported position of the yarn carrier Iii on the adapter 14 whether or not a notch 24 and interfitting lug 26 were used.

The arrangement of the adapters M and supported yarn carriers ill for stacking during a package dyeing operation is illustrated in Fig. 2 of the drawing, and as previously mentioned, the bottom larger end portion I8 of the adapters M is further formed for this purpose with a larger diameter recess as at 32 for nesting over the top smaller end of an adjacent adapter and supported yarn carrier in stacking so as to provide a seal at this point during the package dyeing operation. This recess 32 is shown in the drawing with a squarely disposed end face and side walls which will usually be found to be the most satisfactory form, although some dye machines have spindles fitted with bases of more irregular contour, and the recess 32 may be just as readily shaped to fit this contour in such in stance. The conical form of the yarn carrier l9 and of the adapter Hi provides for seating the carrier l8 tightly on the adapter i4 and the above noted nested arrangement during stacking insures that this tight seating is obtained. The conical form further provides for ready removal of the yarn carrier Hi from the adapter l4 after the dyeing operation has been completed.
